During surgical debridement for scrotal Fournier Gangrene, the testicles and other structures within the ___ can almost always be spared, although loss of tissue in the abdominal wall may be extensive because of bacterial spread along fascial planes.

Severe pruritus is the hallmark of scabies, often accentuated at night or after bathing. In both genders, the genital areas are commonly affected. Small erythematous and pruritic papules are present, and excoriations with secondary bacterial infection may occur. Thin, gray or white burrows may be visible and are pathognomonic for scabies infestation. Crusted scabies affecting genital skin presents as it does in other anatomic sites: with thickly crusted plaque(s)

SCCis usually has an indolent clinical course and rarely progresses to invasive disease. When it occurs on mucosal surfaces of the male genitalia, most notably the glans penis of uncircumcised men, this entity is referred to as erythroplasia of Queyrat

10

Primary treatment of SCCis involves either __ or ___. For accessible areas, such as the scrotum, simple excision with a ___ margin is favored. For areas where tissue preservation is more critical, __,__ and__ may play a role Topical treatment with either __ or ___ can be effective for management of selected cases of SCCis involving the genitalia, although response is variable and the risk of recurrence is higher than with surgical treatmet

Primary treatment of SCCis involves either surgical excision or tissue ablation. For accessible areas, such as the scrotum, simple excision with a 5-mm margin is favored (Bissada, 1992; Margolis, 2002). For areas where tissue preservation is more critical, Mohs microsurgery, laser therapy, and cryoablation may play a role  Topical treatment with either 5-fluorouracil or imiquimod 5% can be effective for management of selected cases of SCCis involving the genitalia, although response is variable and the risk of recurrence is higher than with surgical treatme

14

Verrucous carcinoma (VC) should/should not be treated with primary radiotherapy. VC is a slow-growing, locally aggressive, exophytic, low-grade variant of squamous cell carcinoma that has significant/little metastatic potential. It most commonly occurs in ___ men on the glans or prepuce, although similar lesions can be found on the vulva, vagina cervix, or anus. Treatment is preferably by ___.

Verrucous carcinoma (VC) should not be treated with primary radiotherapy because of the risk of anaplastic transformation. VC is a slow-growing, locally aggressive, exophytic, low-grade variant of squamous cell carcinoma that has little metastatic potential. It most commonly occurs in uncircumcised men on the glans or prepuce, although similar lesions can be found on the vulva, vagina cervix, or anus. Treatment is preferably by local excision. Primary radiotherapy is relatively contraindicated because of the potential for anaplastic transformation with a subsequent increase in metastatic potential.
